consist of plnngers F F arranged at opposite sides of ma sinnlly im the normal use 0E i-lie machine simultaneonsly toward and awa'ylrom each other in suitable guides 6 provided upon the [mine B. Said actuating mill of the sheet or other arlirle D and movable eonmembers are generally formed with eyes j, which ancircle the adjacent ends of the punches .C, and are formed with engaging faces for detachably engaging the, shoulders c and returning said punches to their normsl position. The means for reciprocating the plung'ers or actuating members F preferably consists of eccehtrics f suitably coniiected to said plungers pr actu f sting members, andconnected together by any deni ble power-transmitting mechanism, as gears F,

.Fig. 3, which are also connected to suitable means, as

' pulleys F and a belt F, Fig. 4, for revolving the feedroller E? previously described. 7

' The members G for controlling the operation of the 1 fpunches 0 preferably consist of oppositely arranged substantially vertical fingers supported at opposite des of the path of the sheet or other article D. In

the preferable construction of my invention, the adiaben't ends of the members G at each side of said path.

movable in opposite directions in substantially vertical planes between the punches C and engaging faces of the contiguous actuating member F, and the extremities of said'ends are reduced in thickness and arranged side by side. The opposite ends of the controlling members are suitably connected to any dosirable electrically -operated means for controlling their operation, being .here illustrated as pivoted to the armatures h of-electro nagnets H supported at opposite sides of the guides b forthe actuating members F.

Said armatures h are suitably connected to' springs It, '80 'which retract the arma'tures from the electro'magnets H into engagement with adjustable stops h; The electro-magnets H are usually so connected to the controlling members G that the electro-magnets at one side of one of said guides b control the operation of alter- 85 hate-members G at the same side of the sheet or other article D, and the electro-rnagnets at the other side of said one of the guides control the operation of the 'remaining members G at the same side of said sheet or other article. v A 40 When the controlling members G are in their normal position, the reduced extremities of their adjacent ends are alined with the actuating members F, and no movement of the punches takes place, but, as soon as one of the electro-magnets H attractsits armature h, the controlling member G connected to said armature is nioved lengthwise until the portion thereof adjacent to saidreduced end is alined with the corresponding actuating member, whereupon said actuating member moves said portion of the controlling member toward the sheet or other article D and actuates the correspond I ing punch C to perforate said sheet or cither article. The described actuating and controlling members and electrically-operated means are particularly suitable for use in connection with the remaining parts of my perforating machine, but it is obvious that any other suitable means may be used to actuate and control the punches O, and that, if punches are arranged only atone side of the sheet or article l), the actuating and controlling members and the electrically-operated means at the other side of said sheet or other article are unnecessary. I

The eleetro-magnets H forming the electricallyoperated means of my invention are generally connecied independently to the terminalsn by conduc- 85 tors a, and are connected to a common conductor, is

added with said key.

the frame B, which is connected by a conductor a to one pole of a suitable source of electric energy A, as a battery or dynamo-electric machine. The opposite pole of said source of electric energy is connected to the the terminal a. Consequently, whenever one of the keys A is actuated, the terminal a provided on said key is engaged with the 7 terminal a and the normally broken electric circuit connected to said key is coniplete or open from the source of electric energy to the electro-magnet for controlling the operation of the corresponding controlling member and punch. Said circuit remains complete or open as long as the fingerpieoe'of said one of the keys A is depressed, and during the depression of said finger-piece, one of the members F successively actuates said punch for perforating the sheet or article D. The length or size of the perforations in the sheet or article D made by any one of the punches and the intervals between successive perforations made by said punch thus correspond to the length of time that the corresponding key is held out of its normal position, andto the interval of time between the successive operations of said key during the execu; tion of a musical selection upon the instrument pro- The construction and operation of my improved per forating machine will now'be readil understood upon reference to the foregoing description.and the accom panying drawings, and, as the construction and arrangement of the component parts of said machine may be more or less varied without departing from the spirit of my-invention, I do not herein specifically limit myself to the exact construction and arrangementjoi said parts.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent,

1. The combination of punches arranged at opposite sides of the path of the article to be perforated and provided with engaging shoulders, oppositely arranged actuating members movable toward each other for actuating the punches, said actuating members havlng faces for engaging the shoulders of the punches and returning the same to their normal position, and controlling members movable betweenthe punches and engaging tuceso! the actuating members, substantially as and for the purpose set forth.

. 2. The combination of punches u'rrunged at opposite sides of the path of the article to be perforated, constantly moving mechanical means for moving the punches in opposite directions for perforating said article, electrically operated controlling members movable between the punches and engaging faces of said means, and a plurality oi movable keys for regulating the operation of the respective members, substantially as and for the purpose set forth.

" 3. The combination of punches arranged at opposite sides of the path or the article to be perforated, oppositely arranged actuating members movable toward each other for actuating the punches to perforate said article, said actuating members being provided with means for returnlag the punches to their normal position, and oppositely arranged controlling members supported at each side of the path of said article and movable in opposite directions -between the punches and engaging faces 0!. the actuating members, substantially as and for the purpose described.

' 4. The combination or a frame provided with guides arrsn at opposite sides 0! the path of the article to be perforated, punches supported by the frame at opposite sides of the path of said article, actuating members movable in the guides for actuating the punches to p'ertorste sold article, oppositely arranged controlling members supported stench side of the path of said srtlcle and movable in opposite directions between the punches and engaging eeepao faces of the actuating members, ehkrtro-inagneta arranged at opposite sides of the guides and connections between the eiectro-magnets and the controlling members, said connections operating to transmit motion from the armatures of the electro-magnets at one side of either of the guides to alternate controlling members movable between engagin faces of the adjacent actuating member and the punches actuated thereby, substantiallyns and for the purpose described.

5.,ihe combination of punches arranged at opposite sides of the path of the article to be perforated, oppositely arranged actuating members movable simultaneously toward each other for actuating the punches to perforate said article, oppositely arranged controlling members m0vablc between the punches and engaging facesot said actuating nu-mbcrs, and a plurality of movable keys independently connected to the controlling members for controlling lheir operation, substantially as set forth,

6 The combination oi! punches arranged at opposite sides 0! the path 01! the article to be perforated and movable iniopposite directions for. perforating said article, oppositely arranged actuating members movable simultaneously toward each other for actuating the punches, controlling members for controlling the operation of the punches, electro-mngneta for controlling the operation 0! the controlling members, and movable keys for controlling the action of the electro-magnets, substantially as and for the purpose set forth.

In testimony whereof I have hereunto signed my name in the presence 0.! two attesting witnesses, at Syracuse, in the county of Onondaga in the State of New York this th day of May 1898.
